Market during the period commencing with the Execution Date and ending with the third trading day prior to Closing Date (the Execution Stock Price) is greater than one hundred and twenty-two per cent (122%) times $2.32 (the
Upper Collar Range), or $2.83 per share, the number of shares of common stock of Covalent shall be equal to the quotient obtained by dividing (w) ($13,000,000 by (x) the Upper Collar Range, and

(B) if the Execution Stock Price is less than seventy eight per cent (78%) times USD $2.32 (the Lower Collar Range), or $1.81 per share,

Stockholders option, either (A) by wire transfer of immediately available funds to the bank and account designated by Covalent in writing to Representative (as defined herein) or (B) by transfer to Covalent of such number of shares

Worth Statement (as hereinafter defined)

have been disputed as provided herein, within five business days after the expiration of the 60 day review and audit
period set forth in subparagraph 2(b)(iii), and (B) if any amounts or items shown on the Net Worth Statement have been disputed, within five business days following the resolution of all such disputed amounts or items as provided herein,
provided, however, that a Stockholder may opt by written notice to Covalent to pay such deficiency with Holdback Shares, in which event that portion of such deficiency paid with Adjustment Holdback Shares shall not be due until the Adjustment
Holdback Shares are issued to the Stockholder under Section 2(a)(iv). As used in this Agreement, the term Net Worth means the amount by which the sum of the book value of the assets of Remedium and the Remedium Subsidiaries (as
hereinafter defined) on a consolidated basis exceeds the sum of the book value of the liabilities of Remedium and the Remedium Subsidiaries on a consolidated basis, all as recognized, calculated and determined in accordance with Finnish GAAP
consistently applied with prior periods and reconciled to US GAAP. For purposes of determining Net Worth, up to $300,000 in fees and expenses incurred by Remedium for legal, accounting and investment banking services directly related to
the consummation of the transactions contemplated hereby (Transaction Expenses), shall be disregarded, and all Taxes (as hereinafter defined) of Remedium attributable to the period ending on or prior to the Closing Date shall be accrued
in full.

(ii) It is the intention of the parties that, at the Closing Date, neither Remedium nor any of the Remedium Subsidiaries shall
have any liabilities for borrowed money (Debt). In the event there shall be any Debt outstanding at the Closing Date, the amount of such Debt, less up to $150,000 in Transaction Expenses, shall be reduced from the Exchange Price, at the
option of each Stockholder, either from (A) the Cash Consideration or (B) by reducing the Debt Holdback Shares by such number of shares of Covalent common stock equal to the quotient obtained by dividing (x) the amount of such Debt by
(y) the Combination Price.

(iii) Within 60 days following the Closing Date (as hereinafter defined), Covalent shall prepare and
deliver to Representative a balance sheet setting forth the Closing Net Worth (the Net Worth Statement), which Net Worth Statement shall set forth in reasonable detail the determination and calculation of the Closing Net Worth. If and to
the extent not within the control of Covalent, then for purposes of preparing the Net Worth Statement, Representative shall make reasonably available to Covalent (and Covalents accountants, attorneys, agents, and representatives) during normal
business hours, the books and records (including any accountants work papers) of Remedium and the Remedium Subsidiaries, upon reasonable advance notice to Representative, and shall otherwise cooperate in good faith with Covalent with respect
to the preparation of said Net Worth Statement. For a period of 30 days after receipt by Representative of the Net Worth Statement, Stockholders shall have the right to review such Net Worth Statement and, in connection therewith, shall have access
during normal business hours, to the books and records (including any accountants work papers) of Remedium and the Remedium Subsidiaries. Unless Covalent shall receive notice from Representative within such 30 day period to the effect that the
Stockholders dispute one or more amounts or items shown on the Net Worth Statement, the Net Worth Statement (including the determination and calculation of the Closing Net Worth set forth in the Net Worth Statement) shall be final, conclusive and
binding on the parties hereto. Any such notice from Representative to Covalent disputing one or more amounts or items on the Net Worth Statement as aforesaid shall specify in reasonable detail the nature and amount of said dispute or disputes.

Stockholders dispute one or more amounts or items shown on the Net Worth Statement, then Covalent and Stockholders (with the Representative acting as their representative) shall promptly thereafter meet in good faith to attempt to resolve any and
all such disputed amounts or items. If and to the extent Covalent and Stockholders resolve any such disputed amount or item, then (x) such resolution shall be set forth in a writing signed by Covalent and Stockholders, and (y) if such
resolution would require Stockholders to make a payment to Covalent pursuant to subparagraphs 2(b)(i) or 2(b)(ii), then Stockholders shall make such payment as provided in subparagraphs 2(b)(i) or 2(b)(ii). If and to the extent Covalent and
Stockholders are unable to agree upon a resolution of any disputed amount or item within 15 days after receipt by Covalent of Representatives notice regarding the existence of such disputed amount or item, then such disputed amount or item
shall be resolved by an independent nationally recognized accounting firm, selected by mutual written agreement of Covalent and Representative, which is not then providing, and has not provided at any time during the period commencing one-year prior
to the Closing Date through the date of their determination pursuant to this subparagraph 2(b)(iv), services to any of (i) Covalent or any of its affiliates or (ii) Remedium or any of its affiliates (Independent
Accountants).Upon their appointment, the Independent Accountants shall certify to Covalent and Representative in writing that they satisfy the foregoing qualifications. If Covalent and Representative are unable to agree on mutually
acceptable Independent Accountants during the aforesaid 15 day period, then such Independent Accountants shall be selected, within ten days thereafter, by mutual agreement of Covalents independent public accountant and Remediums
independent public accountants, joint notice of which appointment shall be provided by such accountants to Covalent and Representative. Unless otherwise agreed by Covalent and Representative, Covalent and Representative, on behalf of the
Stockholders, shall each have the opportunity to make a written submission to the Independent Accountants with respect to the disputed amounts or items setting forth their positions and analysis, along with reasonable supporting documentation (which
may include this Agreement, the Net Worth Statement and Covalents notice disputing the same, and any agreements of Covalent and Stockholders resolving any disputes with respect thereto), provided that such submissions are made within ten
business days after either (x) the date on which Covalent and Representative mutually agree to such Independent Accountants, or (y) dates on which Covalent and Representative, respectively, receive the aforesaid joint notice of the
appointment of the Independent Accountants, as the case may be. Unless otherwise agreed in writing by Covalent, Stockholders and the Independent Accountant, the Independent Accountants shall resolve the disputes based solely on the written
submission or submissions received by the Independent Accountants, and there shall be no oral presentations. Covalent and Representative shall instruct the Independent Accountants to promptly resolve such disputes and provide joint written notice of
the resolutions of such disputes (which resolutions shall include a determination of the amounts or remaining amounts, if any, payable by Stockholders under subparagraphs 2(b)(i)) or 2(b)(ii), simultaneously to Covalent and Representative. The
resolution of such disputed amounts and items by the Independent Accountants shall be final, conclusive and binding upon all parties. The fees and expenses of the Independent Accountants shall be borne equally by Covalent, on one hand, and the
Stockholders, on the other hand.

(c) It is the intention of the parties that Covalents Net Worth (as hereinafter defined) at the
Closing (the Covalents Closing Net Worth) be equal or greater than $6,974,689, constituting Covalents Net Worth at September 30, 2005, based on its financial

paid, at Covalents option either (i) by wire transfer to the Representative of immediately available funds, to be allocated among the Stockholders in accordance with the percentages set forth opposite each Stockholders name on
Schedule 4(a), or (ii) by issuance to the Stockholders (to be allocated among the Stockholders in accordance with the percentages set forth opposite each Stockholders name on Schedule 4(a)) the number of shares of common
stock of Covalent equal to the quotient obtained by dividing (w) the amount of such deficiency by (x) the Combination Price. Such payment or issuance of stock shall be as follows: (A) if no amounts or items shown on the statement of
Covalents Closing Net Worth have been disputed as provided herein, within five (5) business days after the expiration of the 60 day period referred to below following the Closing Date for preparation of the statement of Covalents
Closing Net Worth, and (B) if any amounts or items show on the statement of Covalents Closing Net Worth have been disputed as provided herein, within five (5) business days following the resolution of all such disputed amounts or
items as provided herein. As used in this Agreement, the term Covalents Net Worth is the amount by which the sum of the book value of the assets of Covalent and Covalent Subsidiaries (as hereinafter defined) on a consolidated basis
exceeds the sum of the book value of the liabilities of Covalent and Covalent Subsidiaries on a consolidated basis, all as recognized, calculated and determined in accordance with U.S. GAAP consistently applied with prior periods. For purposes of
determining Covalents Net Worth, the fees and expenses incurred by Covalent for legal, accounting and investment banking services directly related to the consummation of the transactions contemplated hereby, as well as any applicable transfer
and stamp taxes, shall be disregarded. Covalents Closing Net Worth shall be calculated by Covalent within 60 days following the Closing Date. Such calculation of Covalents Closing Net Worth by Covalent shall be subject to review by the
Stockholders for a period of 30 days after receipt by Representative of such calculation, together with access to Covalent (and Covalents accountants, attorneys, agents and representatives) during normal business hours, the books and
records (including any accountants work papers) of Covalent and the Covalent Subsidiaries. Unless Covalent shall receive notice from Representative within such 30 day period to the effect that the Representative disputes one or more amounts or items
shown on the calculation of Covalents Closing Net Worth, such calculation shall be final, conclusive and binding on the parties hereto. Any such notice from Representative to Covalent disputing one or more amounts or items on Covalents
Closing Net Worth as aforesaid shall specify in reasonable detail the nature and amount of said dispute or disputes. If Covalent receives notice from Representative within the aforementioned 30 day period that Representative disputes the calculation
of Covalents Closing Net Worth, such dispute shall be resolved in accordance with the proceeding set forth subparagraph 2(b)(iv).

pay in full the amount of the settlement and all associated expenses and the indemnified party is furnished with either (A) security reasonably satisfactory to the indemnified party that the indemnifying party will in fact pay such amount and
expenses, or (B) a full release from the claimant in form and substance reasonably satisfactory to the indemnified party.

(ii) In
the event that the indemnified party asserts the existence of any Deficiency, the indemnified party shall give written notice to the indemnifying party of the nature and amount of the Deficiency asserted. The indemnified party shall reasonably
cooperate with such actions as the indemnifying party may seek to take to mitigate the impact of any alleged breach. Such request shall not be deemed to constitute an admission of liability on the part of the indemnifying party. If the indemnifying
party, within a period of 15 business days after the giving of such notice by the indemnified party, shall not give written notice to the indemnified party announcing its intention to contest such assertion of the indemnified party (such notice by
the indemnifying party being hereinafter called the Contest Notice), such assertion of the indemnified party shall be deemed accepted and the amount of the Deficiency shall be deemed established. In the event, however, that a Contest
Notice is given to the indemnified party within said 15-day period, then the contested assertion of a Deficiency may be established by judicial determination.

(iii) The indemnified and indemnifying parties may agree in writing, at any time, as to the existence and amount of a Deficiency, and, upon the execution of such agreement, such Deficiency shall be deemed established.

(f) Payment of Deficiencies. The indemnifying party hereby agrees to pay the amount of each established Deficiency to the
indemnified party within five business days after the final establishment thereof. Any amounts not paid by the indemnifying party when due under this subparagraph 16(f) shall bear interest from the due date thereof until the date paid at a rate
equal to the prime rate as published from time to time in The Wall Street Journal. At the option of the indemnifying party, the payment of any established Deficiency can be made in cash or in shares of common stock of Covalent
which shall be valued at the Combination Price.If Covalent pays any deficiencies in shares of common stock it shall use commercially reasonable efforts to promptly register those shares with the SEC and under an effective Registration
Statement.

(g) Limitation. With the exception of (A) any Deficiencies resulting from any
misrepresentation or breach of representation or warranty on the part of the Stockholders contained in Paragraph 4 or subparagraphs 5(u) and 5(w) herein, (B) any Deficiencies resulting from any misrepresentation or breach of representation or
warranty on the part of Covalent contained subparagraphs 6(u) and 6(w) herein, or (C) any claims of fraud on the part of any party to this Agreement, (x) there shall be no liability for any Deficiencies resulting from any misrepresentation
or breach of representation or warranty on the part of either the Stockholders under Paragraph 5 or Covalent under Paragraph 6 unless and until the aggregate of all such Deficiencies attributed to the Stockholders cumulatively or Covalent, whichever
is applicable, exceeds $200,000, in which event there shall be liability for all such Deficiencies, (Y) neither party shall be liable or otherwise responsible for that portion of any such Deficiencies attributed to the Stockholders or Covalent,
whichever is applicable, that exceeds an amount equal to $8,000,000 which shall be the maximum cumulative, aggregate liability of the Stockholders collectively or Covalent, whichever is applicable, hereunder, and (Z) no claim shall be asserted
or brought hereunder in respect to any such Deficiencies after the second anniversary of the Closing Date, provided, however, that claims asserted hereunder by written notice prior to expiration of time limit may be prosecuted or arbitrated until
their conclusion. The rights of indemnification provided for in this Paragraph 16 shall be the sole and exclusive remedy of Covalent Indemnified Parties and of the Remedium Indemnified Parties, whichever is applicable, with respect to any claims
arising out of or relating to this Agreement.

18. [intentionally omitted]

19. Further
Assurances. Covalent and Stockholders agree to execute and deliver all such other instruments and take all such other action as any party may reasonably request from time to time, after the date hereof and without payment of further
consideration, in order to effectuate the transactions provided for herein. The parties shall cooperate fully with each other and with their respective counsel and accountants in connection with any steps required to be taken as part of their
respective obligations under this Agreement, including, without limitation, the preparation of financial statements and preparation and filing of Tax Returns.

20. Dispute Resolution.

(a) In the event of a dispute between the parties, including indemnification
claims pursuant to Section 16, the parties shall first promptly attempt in good faith to resolve such dispute for a period of not less than 30 calendar days. If such good faith efforts are not successful within such 30-day period, at any time
thereafter, any party may give the other written notice of a dispute (a Dispute Notice), the parties shall attempt in good faith to agree to the appointment of an independent mediator (a Mediator) to assist the parties in
resolving the dispute. Should the parties agree to a Mediator, the matter shall be referred to such Mediator for resolution in accordance with the usual practices and procedures of such Mediator; provided,



46



---

however, that no party shall have an obligation to participate in any mediation after a date which is thirty calendar
(30) days after the applicable Dispute Notice was served. The parties shall cooperate with the Mediator and shall provide any relevant information requested by the Mediator. If the Parties cannot agree on the selection of a Mediator within
twenty (20) calendar days after delivery of the Dispute Notice, or if the dispute is not resolved by the Mediator as provided herein, then the dispute shall be determined by arbitration in accordance with the provisions of subparagraph 20(b)
hereunder.

(b) Any dispute which is not settled or otherwise resolved through the provisions of subparagraph 20(a) above shall be
determined by arbitration in Wilmington, Delaware by a single arbitrator in accordance with the rules of the American Arbitration Association (AAA) or any other rules agreed upon by the parties, except that (i) every person named on
any list of potential arbitrators shall be a neutral and impartial lawyer with excellent academic and professional credentials (i) who has practiced law for at least 15 years, specializing in either general commercial litigation or general
corporate and commercial matters, and (ii) who has had experience, and is generally available to serve, as an arbitrator, and (b) each party shall be entitled to strike on a peremptory basis, for any reason or no reason, any or all of the
names of potential arbitrators on any list submitted to the party by the AAA as well as any person selected by the AAA to serve as an arbitrator by administrative appointment. In the event the parties cannot agree on the selection of the arbitrator
from the one or more lists submitted by the AAA within thirty (30) calendar days after the AAA transmits to the parties its first list of potential arbitrators, AAA shall nominate three persons who meet the criteria set forth herein. Each party
shall be entitled to strike one of such three nominees on a peremptory basis within five (5) calendar days after its receipt of such list of nominees, indicating its order of preference with respect to the remaining nominees. If two of such
nominees have been stricken by the parties to the dispute, the unstricken nominee shall be the arbitrator. Otherwise, the selection of the arbitrator shall be made by the AAA from the remaining nominees in accordance with the parties mutual
order of preference, or by random selection in the absence of a mutual order of preference. The arbitrator shall base his or her award on the terms of this Agreement, on applicable law and judicial precedent, shall include in such award the findings
of fact and conclusions of law upon which the award is based and shall not grant any remedy or relief that a court could not grant under applicable law. The arbitration shall be governed by the substantive laws of the State of Delaware applicable to
contracts made and to be performed therein, without regard to conflicts of laws rules. Judgment on the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.

(c) If any party to a dispute fails to proceed with the dispute resolution procedures set forth in this Paragraph 20 or unsuccessfully seeks to stay such
proceedings, or fails to comply with any arbitration award, or is unsuccessful in vacation or modifying the award pursuant to a petition or application for judicial review, the other party shall be entitled to be awarded costs, including reasonable
attorneys fees, paid or incurred by such other party in successfully compelling such proceedings or defending against the attempt to stay, vacate or modify such arbitration award and/or successfully defending or enforcing the award.

partial exercise of any right, remedy, power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any
occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No waiver shall be effective unless it is in writing and is signed by the party asserted to have granted such waiver.

(b) Controlling Law. This Agreement and all questions relating to its validity, interpretation, performance and enforcement (including, without
limitation, provisions concerning limitations of actions), shall be governed by and construed in accordance with the laws of the State of Delaware, notwithstanding any conflict-of-laws doctrines of such state or other jurisdiction to the contrary,
and without the aid of any canon, custom or rule of law requiring construction against the draftsman.

5.1. Restrictive Covenants.

(a) Non-Compete. Except if Executives employment is terminated by the Company without Cause or by Executive for Good reason, Executive shall not, during the Restricted Period, in the United States or any
other place where the Company, its subsidiaries or affiliates conduct business, directly or indirectly (except in Executives capacity as an employee of the Company, and in the best interests of the Company) do any of the following without the
prior written consent of the Board:

(i) engage or participate in any Competing Business;

63



---

distributor of the Company at any time during the Restricted Period until the expiration of twelve
(12) months from the date such person ceases to have been employed or retained by the Company.

(b) Confidentiality. Executive
recognizes and acknowledges that the Proprietary Information is a valuable, special and unique asset of the business of the Company. As a result, both during the Term and thereafter, Executive shall not, without the prior written consent of the
Company, for any reason either directly or indirectly divulge to any third party or use for his own benefit, or for any purpose other than the exclusive benefit of the Company, any Proprietary Information revealed, obtained or developed in the
course of his employment by the Company; provided, however, that nothing herein contained shall restrict Executives ability to make such disclosures during the Term as may be necessary or appropriate to the effective and efficient
discharge of his duties as an employee hereunder or as such disclosures may be required by law. If Executive or any of his representatives become legally compelled to disclose any of the Proprietary Information, Executive will provide the Company
with prompt written notice so that the Company may seek a protective order or other appropriate remedy.

(c) Property.

(i) All right, title and interest in and to Proprietary Information shall be and remain the sole and exclusive property of the Company.
During the Term, Executive shall not remove from the Companys offices or premises any documents, records, notebooks, files, correspondence, reports, memoranda or similar materials of or containing Proprietary Information, or other materials or
property of any kind belonging to the Company unless necessary or appropriate in accordance with the duties and responsibilities required by or appropriate for his position and, in the event that such materials or property are removed, all of the
foregoing shall be returned to their proper files or places of safekeeping as promptly as possible after the removal shall serve its specific purpose. Executive shall not make, retain, remove and/or distribute any copies of any of the foregoing for
any reason whatsoever except as may be necessary in the discharge of his assigned duties and shall not divulge to any third person the nature of and/or contents of any of the foregoing or of any other oral or written information to which he may have
access or with which for any reason he may become familiar, except as disclosure shall be necessary in the performance of his duties; and upon the termination of his employment with the Company, he shall leave with or return to the Company all
originals and copies of the foregoing then in his possession, whether prepared by Executive or by others.

(ii) Executive
agrees that all the Intellectual Property will be considered works made for hire as that term is defined in Sections 101 and 201 of the Copyright Act (17 U.S.C. §§ 101 and 201) and that all right, title and interest in such
Intellectual Property will be the sole and exclusive property of the Company. To the extent that any of the Intellectual Property may not by law be considered a work made for hire, or to the extent that, notwithstanding the foregoing, Executive
retains any interest in the Intellectual



64



---

Property, Executive hereby irrevocably assigns and transfers to the Company any and all right, title, or
interest that Executive may have in the Intellectual Property under patent, copyright, trade secret and trademark law, in perpetuity or for the longest period otherwise permitted by law, without the necessity of further consideration. The Company
will be entitled to obtain and hold in its own name all copyrights, patents, trade secrets, and trademarks with respect to such Intellectual Property. Executive further agrees to execute any and all documents and provide any further cooperation or
assistance reasonably required by the Company to perfect, maintain or otherwise protect its rights in the Intellectual Property. If the Company is unable after reasonable efforts to secure Executives signature, cooperation or assistance in
accordance with the preceding sentence, whether because of Executives incapacity or any other reason whatsoever, Executive hereby designates and appoints the Company or its designee as Executives agent and attorney-in-fact, to act on his
behalf, to execute and file documents and to do all other lawfully permitted acts necessary or desirable to perfect, maintain or otherwise protect the Companys rights in the Intellectual Property. Executive acknowledges and agrees that such
appointment is coupled with an interest and is therefore irrevocable.

5.2. Rights and Remedies Upon Breach.

(a) Specific Enforcement. Executive acknowledges that the Restrictive Covenants are reasonable and necessary to protect the legitimate interests of
the Company and its affiliates and that the Company would not have entered into this Agreement in the absence of such restrictions. Executive also acknowledges that any breach by him, willfully or otherwise, of the Restrictive Covenants will cause
continuing and irreparable injury to the Company for which monetary damages would not be an adequate remedy. Executive shall not, in any action or proceeding to enforce any of the provisions of this Agreement, assert the claim or defense that such
an adequate remedy at law exists. In the event of any such breach by Executive, the Company shall have the right to enforce the Restrictive Covenants by seeking injunctive or other relief in any court, without any requirement that a bond or other
security be posted, and this Agreement shall not in any way limit remedies of law or in equity otherwise available to the Company. If an action at law or in equity is necessary to enforce or interpret the terms of this agreement, the prevailing
party shall be entitled to recover, in addition to any other relief, reasonable attorneys fees, costs and disbursements.

(b)
Accounting. If Executive willfully breaches, or threatens to commit a breach of any of the Restrictive Covenants, the Company will have the right and remedy to require Executive to disgorge all compensation, profits, monies, accruals,
increments or other benefits derived or received by Executive as the result of any action constituting a breach of the Restrictive Covenants. This right and remedy will be in addition to, and not in lieu of, any other rights and remedies available
to the Company under law or in equity.

5.3. Judicial Modification. If any court determines that any of the Restrictive Covenants,
or any part thereof, is unenforceable because of the duration or scope of such provision, such court shall have the power to modify such provision and, in its modified form, such provision shall then be enforceable.



65



---

5.4. Disclosure of Restrictive Covenants. Executive agrees to disclose the existence and terms of
the restrictive covenants set forth in this Section 5 to any employer that Executive may work for during the Restricted Period and to allow the Company to do the same.

5.5. Acknowledgments. Executive acknowledges that the Restrictive Covenants contained in Section 5.1(a) are included herein in order
to induce the Company to employ Executive pursuant to the other terms of this Agreement and to agree to the provisions of Section 6.2. Executive further acknowledges that the duration and geographic scope of Section 5.1(a)
are reasonable given the nature of this Agreement.

5.6. Enforceability. If any court holds the Restrictive Covenants unenforceable
by reason of their breadth or scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the right of the Company to the relief provided above in the courts of any other jurisdiction within the
geographical scope of such Restrictive Covenants.

SECTION 6. Termination.

6.1. Generally. If Executives employment with the Company is terminated during the Term for any reason other than as specified in
Section 6.2 (including termination by the Company for Cause, as a result of Executives death, as a result of Executives Disability, or by Executive without Good Reason), then the Companys obligation to Executive will be
limited solely to the payment of (a) all accrued but unpaid Base Salary and Benefits through the date of such termination, and (b) the payment of any accrued but unpaid bonus payable under Section 4.1 with respect to a fiscal
year of the Company ending prior to such termination. All Base Salary and Benefits shall cease at the time of such termination, subject to the terms of any benefits or compensation plans then in force and applicable to Executive, and the Company
shall have no further liability or obligation hereunder by reason of such termination.

6.2. Termination Without Cause or With Good
Reason. If Executives employment by the Company is terminated during the Term by the Company without Cause or by Executive with Good Reason, Executive will be entitled to (a) the payment of all accrued but unpaid Base Salary and
Benefits through the date of such termination, (b) the payment of any accrued but unpaid bonus payable under Section 4.1 with respect to a fiscal year of the Company ending prior to such termination, (c) a continuation of group
health coverage for Executive for the Severance Period (and, to the extent covered immediately prior to the date of Executives termination, his dependents) with the contributions paid by the Company and the Executive continuing on the same
basis as in effect on the date of Executives termination (as such contributions may be changed in accordance with changes for similarly situated employees during the relevant time period); (d) the payment for the Severance Period of
monthly severance payments equal to one-twelfth of his Base Salary as of the date



66



---

of such termination, and (e) vesting of all of Executives stock options, to the extent not already vested.
Upon the end of the Severance Period, all benefits described in this Section 6.2 (c), (d) and (e) will cease and the Company shall have no further liability or obligation by reason of such termination. If Executive violates the
provisions of Section 5.1(a), the Companys obligations to provide the benefits described in Section 6.2(c), (d) and (e) shall cease and be rendered a nullity until such time that Executive is again in
compliance with Section 5.1(a).

6.3. Termination Procedures. Any termination of Executives employment by the Company or
by Executive during the Term (other than termination pursuant to death) shall be communicated by written notice of termination to the other party and shall set forth the circumstances that provide the basis for Executives termination. The date
of termination shall be (a) the date of death, if Executives employment is terminated by death or (b) the date of the notice of termination or the expiration of any applicable remedy period, whichever is later.

SECTION 7. Expenses. The Company will pay or reimburse Executive for reasonable and necessary expenses directly incurred in the course of his employment by
the Company in accordance with the standard policies and practices of the Company. Executive shall be entitled to fly business class (or first class if business class is not offered) on all transcontinental flights.

this Agreement.

2.7 Notices. In the event of a transaction that would constitute a Change of Control but for the provisions of
Section 1(f)(i)(A) regarding contractual restrictions on the acquiror, the Company will give written notice to the Executive that no Change of Control has occurred. Likewise, in the event that such contractual restrictions are subsequently
removed, the Company will give written notice to the Executive that a Change of Control has occurred or will occur as of the effective date of the removal of such restrictions. Any termination by the Company for Cause or by the Executive for Good

Form and Timing of Severance Benefits. The Severance Benefits described in Section 2.3 hereof shall be paid in cash to the Executive in a single lump sum as soon as practicable following the Effective Date of Termination, but in no event
beyond thirty (30) days from such date. Any payment required under this Section 3.1, or any other provision of this Agreement, that is not made in a timely manner will bear interest at a rate equal to one hundred twenty percent
(120%) of the applicable federal rate, as in effect under Section 1274(d) of the Code for the month in which the payment is required to be made.

3.2 Withholding of Taxes. The Company shall be entitled to withhold from any amounts payable under this Agreement all taxes as legally shall be required (including, without limitation, any United States Federal
taxes, and any other state, city, or local taxes).

ARTICLE 4. EXCISE TAX GROSS UP

4.1 Equalization Payment. In the event that the Executive becomes entitled to Severance Benefits, if any of the Executives Total Payments
will be subject to the tax (the Excise Tax) imposed by Section 4999 of the Code (or any similar tax that may hereafter be imposed), the Company shall pay to the Executive in cash an additional amount (the Gross-up
Payment) such that the net amount retained by the Executive after deduction of any Excise Tax on the Total Payments and any federal, state, and local income tax and Excise Tax upon the Gross up Payment provided for by this Section 4.1,
shall be equal to the Total Payments. Such payment shall be made by the Company to the Executive as soon as practicable following the Effective Date of Termination, but in no event beyond thirty (30) days from such date.



76



---

4.2 Tax Computation. For purposes of determining whether any of the Total Payments will be subject
to the Excise Tax and the amounts of such Excise Tax:

(a) Any other payments or benefits received or to be received by the Executive in
connection with a Change in Control of the Company or the Executives termination of employment (whether pursuant to the terms of this Agreement or any other plan, arrangement, or agreement with the Company, or with any Person whose actions
result in a Change in Control of the Company or any Person affiliated with the Company or such Persons) shall be treated as parachute payments within in the meaning of Section 280G(b)(2) of the Code, and all excess parachute
payments within the meaning of Section 280G(b)(1) shall be treated as subject to the excise tax, unless in the opinion of tax counsel selected by the Companys independent auditors and acceptable to the Executive, such other payments
or benefits (in whole or in part) do not constitute parachute payments, or unless such excess parachute payments (in whole or in part) represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of
the Code in excess of the base amount within the meaning of Section 280G(b)(3) of the Code, or are otherwise not subject to the excise tax;

(b) The amount of the Total Payments which shall be treated as subject to the Excise Tax shall be equal to the lesser of (i) the total amount of the Total Payments; or (ii) the amount of excess parachute payments within the
meaning of Section 280G(b)(1) (after applying clause (a) above); and

(c) The value of any non-cash benefits or any deferred
payment or benefit shall be determined by the Companys independent auditors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

For purposes of determining the amount of the Gross Up Payment, the Executive shall be deemed to pay Federal income taxes at the highest marginal rate of Federal income taxation in the calendar year in which the Gross
Up Payment is to be made, and state and local income taxes at the highest marginal rate of taxation in the state and locality of the Executives residence on the Effective Date of Termination, net of the maximum reduction in Federal income
taxes which could be obtained from deduction of such state and local taxes.

4.3 Subsequent Recalculation. In the event the Internal
Revenue Service adjusts the computation of the Company under Section 4.2 hereof, so that the Executive did not receive the greatest net benefit, the Company shall reimburse the Executive for the full amount necessary to make the Executive
whole, plus an appropriate market rate of interest, as determined by the Companys independent auditors.

ARTICLE 5. THE COMPANYS PAYMENT
OBLIGATION

5.1 Payment Obligations Absolute. The Companys obligation to make the payments and the arrangements provided
for herein shall be absolute and unconditional, and shall not be affected by any circumstances, including, without limitation, any offset, counterclaim, recoupment, defense, or other right which the Company may have against the Executive or anyone
else, except those arising under this Agreement. All amounts payable by the Company hereunder shall be paid without notice or demand. The Executive shall not be obligated to seek other employment in mitigation of the amounts payable or arrangements
made under any provision of this Agreement, and the obtaining of any such other employment shall in no event effect any reduction of the Companys obligations to make the payments and arrangements required to be made under this Agreement,
except to the extent provided in Sections 2.3(b) hereof.

5.2 Contractual Rights to Benefits. This Agreement establishes and vests
in the Executive a contractual right to the benefits to which he is entitled hereunder. However, nothing herein contained shall require or be deemed to require, or prohibit or be deemed to prohibit, the Company to segregate, earmark, or otherwise
set aside any funds or other assets, in trust or otherwise, to provide for any payments to be made or required hereunder.

ARTICLE 6. LEGAL REMEDIES

6.1 Payment of Legal Fees. To the extent permitted by law, the Company shall pay all legal fees, costs, including costs of
litigation, prejudgment interest, and other expenses, incurred in good faith by the Executive as a result of the Companys wrongful refusal to provide the Severance



77



---

Benefits to which the Executive becomes entitled under this Agreement, or as a result of the Companys
unsuccessfully contesting the validity, enforceability, or interpretation of this Agreement, or as a result of any conflict between the parties pertaining to this Agreement in which the Executive is the prevailing party, or which is settled prior to
the entry of a final judgment from which no appeal can be taken.

6.2 Arbitration. The Executive shall have the right and option to
elect (in lieu of litigation) to have any dispute or controversy arising under or in connection with this Agreement settled by final and binding arbitration, conducted before a panel of three (3) arbitrators sitting in a location selected by
the Executive within fifty (50) miles from the location of his job with the Company, in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the award of the arbitrator in any court having
proper jurisdiction.

All expenses of any such arbitration in which the Executive is the prevailing party, as determined by the arbitrators, including the
fees and expenses of the counsel for the Executive, shall be borne by the Company.

ARTICLE 7. SUCCESSORS

7.1 Assumption of Companys Obligations. The Company will require any successor (whether direct or indirect, by purchase, merger,
consolidation, or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform the Companys obligations under this Agreement in the same manner and to the same extent that the
Company would be required to perform them if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effective date of any such succession shall entitle the Executive to compensation from the
Company in the same amount and on the same terms as he would be entitled to hereunder if he had terminated his employment with the Company voluntarily for Good Reason. The date on which any such succession becomes effective shall be deemed the
Effective Date of Termination.

7.2 Payment to Beneficiary. This Agreement shall inure to the benefit of and be enforceable by the
Executives personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees, and legatees. If the Executive should die while any amount would still be payable to him hereunder had he continued to live,
all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement, to the Executives Beneficiary. If the Executive has not named a Beneficiary, then such amounts shall be paid to the
Executives devisee, legatee, or other designee, or if there is no such designee, to the Executives estate.

ARTICLE 8. MISCELLANEOUS

8.1 Entire Agreement. This Agreement contains the entire understanding respect to the subject matter hereof.

8.2 Severability. In the event any provision of this Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall
not affect the remaining parts of the Agreement, and the Agreement shall be construed and enforced as if the illegal or invalid provision had not been included. Further, the captions of this Agreement are not part of the provisions hereof and shall
have no force and effect.

8.3 Modification. No provision of this Agreement may be modified, waived, or discharged unless such
modification, waiver, or discharge is agreed to in writing and signed by the Executive and by an authorized representative of the Company, or by the respective parties legal representatives and successors.

8.4 Applicable Law. To the extent not preempted by the laws of the United States, the laws of the Commonwealth of Pennsylvania shall be the
controlling law in all matters relating to this Agreement.

(a) Specific Enforcement. The Covered Person acknowledges that the Restrictive Covenants are reasonable and necessary to protect the legitimate
interests of the Company and its affiliates and that the Company would not have closed under the Combination Agreement in the absence of such restrictions. The Covered Person also acknowledges that any breach by him, willfully or otherwise, of the
Restrictive Covenants will cause continuing and



82



---

irreparable injury to the Company for which monetary damages would not be an adequate remedy. The Covered Person shall
not, in any action or proceeding to enforce any of the provisions of this Agreement, assert the claim or defense that such an adequate remedy at law exists. In the event of any such breach by the Covered Person, the Company shall have the right to
enforce the Restrictive Covenants by seeking injunctive or other relief in any court, without any requirement that a bond or other security be posted, and this Agreement shall not in any way limit remedies of law or in equity otherwise available to
the Company. If an action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to recover, in addition to any other relief, reasonable attorneys fees, costs and
disbursements.

(b) Accounting. If the Covered Person willfully breaches, or threatens to commit a breach of any of the Restrictive
Covenants, the Company will have the right and remedy to require the Covered Person to disclose or disgorge to the Company as liquidated damages all compensation, profits, monies, accruals, increments or other benefits derived or received by the
Covered Person as the result of any action constituting a breach of the Restrictive Covenants. This right and remedy will be in addition to, and not in lieu of, any other rights and remedies available to the Company under law.

2.3. Judicial Modification. If any court determines that any of the Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or scope of such provision, such court shall have the power to modify such provision and, in its modified form, such provision shall then be enforceable.

acknowledges that the Restrictive Covenants contained in Section 2 are reasonable, and that there is sufficient consideration received by the Covered Person pursuant to the transactions contemplated by the Combination Agreement to
support these restrictions.

2.6. Enforceability. If any court holds the Restrictive Covenants unenforceable by reason of their
breadth or scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect the right of the Company to the relief provided above in the courts of any other jurisdiction within the geographical scope
of such Restrictive Covenants.

SECTION 3. Miscellaneous.

Riitta Korpela and Agneta Lindevall (each a Stockholder), constituting all of the stockholders of Remedium Oy, a corporation organized under the laws of Finland (Remedium). Pursuant to the terms of the Combination Agreement
the Stockholders have agreed to contribute, convey, transfer and assign to the Company all of the issued and outstanding shares of Remedium at the Closing (as defined in the Combination Agreement). In consideration of the contribution, conveyance,
transfer and assignment of the Shares, at the Closing (as defined in the Combination Agreement), Covalent, among other consideration, will issue to each Stockholder the number of shares of Common Stock of the Company as set forth next to such
Stockholders name on Exhibit A hereto (the Shares).

In order to induce Company to close under the Combination Agreement
and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, without the prior written consent of the Company, the undersigned will not, directly or indirectly offer, sell,
pledge, contract to sell, grant any option to purchase or otherwise dispose of any Shares or other capital stock of the Company, or any securities convertible, exchangeable or exercisable for shares of Common Stock or derivative thereof or request

of the foregoing referred to as a Disposition) for a period of commencing on the Closing Date (as defined in the Combination Agreement) and ending nine calendar months after the Closing Date (the Lock-Up Period). The
foregoing restriction is expressly intended to preclude the undersigned from engaging in any Hedging Transaction or other transaction which is designed to or reasonably expected to lead to or result in a Disposition during the Lock-Up Period even if
the securities would be disposed of by someone other than the undersigned. Hedging Transaction means any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or
call option) with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from the Common Stock.

promulgated under the Securities Act of 1933.

The undersigned agrees that the Company may (i) with respect to any shares for which
the undersigned is the record holder, cause the transfer agent for the Company to note stop transfer instructions with respect to such shares on the transfer books and records of the Company and (ii) with respect to any shares for which the

agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter
agreement. All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of
the undersigned.

may be inferred beyond the matters expressly stated herein. Further, all opinions expressed herein are subject to such exceptions, if any, as are disclosed in the Schedules to the Agreement.

Based upon the foregoing, I am of the opinion that:

in good standing under the laws of Finland.

2. The authorized capital stock of Remedium consists of
 shares of common stock Common Stock), of which there are  shares issued
and outstanding and of record as of the date hereof (the Shares).

Shares. To the best of my knowledge, the Shares have been validly issued, fully paid and nonassessable.

constitutes the legal, valid and binding obligation of each Shareholder, enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,

The foregoing opinions are subject to the following qualifications (in addition to the qualifications, exceptions, limitations and assumptions specified above):

A. My opinions as they relate to the legality, validity, binding effect and/or enforceability of the Agreement and the Lock-Up Agreement are subject to
the qualification that the availability of the remedies of specific performance or injunctive relief, or any other equitable remedy, is subject to the discretion of the court before which a proceeding therefor may be brought, equitable defenses and
the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and other
similar doctrines affecting the enforcement of agreements generally.

to or may take or fail to take on or after the date hereof which, if taken or not taken, would affect or impair the legality, validity, binding effect and/or enforceability of the Agreement or Transaction Documents or the rights and remedies of the
parties thereunder.

D. My opinions as they relate to the legality, validity, binding effect and/or enforceability of the Agreement and the
Lock-Up Agreement are subject to the limitations arising from court decisions involving statutes, public policy and/or principles of equity holding that (i) purported waivers of the benefits of statutory provisions or constitutional or common
law rights and broadly or vaguely stated provisions waiving rights or waivers of unknown future rights or duties imposed by law are or may be void or unenforceable, (ii) under certain circumstances, provisions declaring that the failure to
exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy are invalid, (iii) provisions declaring that the documents may only be amended or waived in writing may be unenforceable to the extent

interest which may prohibit enforcement of certain contractual provisions; and (v) the indemnification and exculpation provisions of the Agreement and Transaction Documents may be unenforceable to the extent that the enforcement of such
provisions is determined to be against public policy.

E. Since it is necessary for the Shareholders to elect their proper remedy in certain
instances, no opinion is expressed or implied that any cumulative remedy provision contained in the Agreement or any of the Transaction Documents is valid or enforceable.



93



---

F. Certain rights, remedies, waivers and indemnities contained in the Agreement and/orthe Transaction
Documents, in addition to those specifically enumerated above, may be limited or rendered ineffective by applicable Finnish laws or judicial decisions governing such provisions, but such laws and judicial decisions do not render the Agreement or the
Lock-Up Agreement invalid as a whole, and there exist, in the Agreement and the Lock-Up Agreement or pursuant to applicable law, legally adequate remedies for a realization of the principle benefits intended to be provided by the Agreement and the
Lock-Up Agreement.

G. In expressing the opinions set forth herein, I have relied, without investigation, upon the assumptions set forth
below:

1. The Shareholders hold the requisite title and rights to the Shares;

2. There has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence; and

3. All parties to the transactions contemplated by the Agreement will act in accordance with, and will refrain from taking any action that is forbidden
by, the terms and conditions of the Transaction Documents.
